Wong Foon Sien (Chinese: 黃寬先; 7 July 1899 – 31 July 1971), also simply known as Foon Sien, was a Canadian journalist and labour activist. He devoted time to a number of civil and human rights organizations, was one of the early leaders of the Chinese Benevolent Association in Vancouver, and was "perhaps the most influential person" in the city's Chinatown. He was sometimes referred to as the "spokesman for Chinatown", or as "mayor of Chinatown" by Vancouverites, to the resentment of some Chinese Canadians in the community.
